Overwatch‘s post-match Play of the Game replays – snapshots of a particular player’s greatest moment of triumph, shared for all to see – are a brilliant little bit of design. So much so that Blizzard don’t want anyone else using them, according to a patent submitted to the US Patent and Trademark Office back in December of 2016.
This month it was made public, although the patent itself is still pending review. While the patent does not seem to restrict post-game replays as a whole, it would prevent other studios from implementing them in the specific method that Blizzard have worked out.
